Peabody Scientific has developed a number of ion sources to meet most all needs in the ion beam research community. These sources produce a wide array of ion species from protons to Uranium and are available as both positive and negative ions.
Each source has its own specific characteristics that makes it the source of choice for a particular application. Once the end user describes the type of experiment to be performed, we can then recommend the source that best fits the requirements.

Positive Ion Sources:
Model PS-100 Duoplasmatron. This is an arc discharge source characterized by high ionization efficiency, high brightness, and low energy spread.
It produces a large number of gaseous ion species. When equipped with the optional expansion cup chamber, corrosive gases such as SF6 can be used with no deleterious effects.
Model PS-133 Cesium Ion Source. This is a surface ionization source that produces intense beams of high purity cesium ions. It is characterized by long life, high beam stability, low energy spread and simple operation. When used on a SIMS instrument it can produce microampere levels of cesium beams in a few 10's of microns beam diameter.
Model PS-230 Penning Source. This is a cold cathode arc discharge source that is used to produce metallic ions by sputtering of the source cathode and to produce multiply charged ions due to the unique characteristics of the arc discharge.
Negative Ion Sources:
Model PS-100 Duoplasmatron. The Duoplasmatron can be used to produce negative ions for direct extraction from the source. Since the arc discharge is rich in negative ions as well as positive ones, by reversing the polarity of the beam extraction voltage, a significant current of negative ions for various species is available.
Model PS-120 Negative Sputter Ion Source This source utilizes cesium to bombard a cathode target made from the material of the desired ion species. Most all elemental ions in the periodic chart can be produced. In addition, a profusion of negative cluster ions is produced.
Model PS-100/Model PS-510 DP Charge Exchange Source The Model PS-100 Duoplasmatron, operating in the positive ion mode, can be used in conjunction with our Model PS-510 Lithium Charge Exchange Cell to produce negative Helium ions through a resonance charge exchange process. The result is microampere levels of negative helium ions at 20 keV beam energy.
